摘要
[目的]研究悬铃果毛制备活性炭纤维的最佳制备条件,及各因素对吸附效果的影响。[方法]以悬铃果毛纤维为材料,采用正交试验方法研究用活化剂浸泡后,经过预氧化、碳化、活化处理后制得活性炭纤维的性能,并研究pH、吸附剂量、温度等对吸附效果的影响。[结果]在活化剂(NH4)2HPO4溶液浓度为15%时浸泡10 h,在200℃下预氧化30 min,在N2保护下置于马弗炉中在800℃下炭化40 min,炭化的升温速率选择10℃/min,最后用饱和水蒸气进行活化,即得到性能良好的活性炭纤维。[结论]活性炭纤维对水体中甲基橙的吸附量为83.56 mg/g,各反应因素对吸附性能的影响程度为:活化方式>炭化时间>炭化温度>活化剂浓度。
[Objective]Study the optimum preparation conditions of activated carbon fiber made from plane tree cones,and the influence of factors on adsorption effect.[Method]This experiment soak plane tree cones in the activator,through the preoxidation,carbonization and activation process,come to activated carbon.the influence of pH,adsorption dose,temperature on the adsorption effect were studied.[Result]Soak 10h in 15% activator（NH4）2HPO4 concentration,preoxidation 30 min at 200 ℃,carbonize 40 min in Muffle furnace at 800 ℃ without oxygen,the heating rate is 10 ℃/min.Finally,activation with saturated water vapor,a good performance activated carbon could be obtained.[Conclusion]Absorption capacity of methyl orange could get 83.56 mg/g.The influence degree sequence of various factors on the adsorption performance was activation method carbonization temperature carbonization time activator concentration.
